Earth-Three (pre-crisis)

History was "backwards": American Christopher Columbus discovered Europe; Great Britain won its freedom from the United States; President John Wilkes Booth was assassinated by a crazed actor named Abraham Lincoln; the United States flag's colors were reversed: black stars on a red field, with alternating blue and black stripes; and all superheroes are supervillains and vice versa.

A Hypertime version of Earth-Three was seen in Another Nail
